Step-by-step explanation:
x³ + 10x² + 25x
= x(x² + 10x + 25)
= x(x + 5)².
You have to divide 18 by 40 which will give you .45 so the unit rate per minute is .45 and i don't know the unit rate per hour I'm sorry!!! i hope this helps!!!
You’re going to want to use the pythagorean theorem (a^2+b^2=c^2). Start with what you know your hypotenuse is 53 ft (c) and one of your sides is 45 ft (a). Plug in the equation: (45^2+b^2=53^2). Next square each side: (2025+b^2=2809). Then: (b^2=784). Finally square root: (b=28) So your answer is x=28 ft.
Answer:
40 units
Step-by-step explanation:
On the number line, the distance between x and y is given by
|x-y|.
To find the distance between -70 and -30 on the number line, we find the absolute value of their difference.
Therefore the distance between -70 and -30 on the number line is 40 units.
